Dr. Pennesi was born in Mount Kisco, New York, and moved to Dallas, Texas at a young age. For college, he moved to the east coast and attended the University of Pennsylvania for his undergraduate studies. There he graduated summa cum laude with a BS in biomedical engineering and was awarded the Herman P. Schwann award in bioengineering for exemplary scholarship.
Dr. Pennesi's interest in degenerative retinal disorders began shortly after his first year in college, when he spent a summer working at the Retina Foundation of the Southwest. He worked under the supervision of Dr. David Birch and saw patients with retinal degenerations such as retinitis pigmentosa as well as studying animal models of this disease.
After college, Dr. Pennesi completed a combined M.D./Ph.D. at Baylor College of Medicine in Houston, Texas. He performed his graduate Ph.D. work in the Department of Neuroscience in the lab of Dr. Samuel Wu. His thesis work focused on identifying new animal models of retinal degeneration. He received numerous awards while in graduate school, including the John J. Trentin Award for earning the highest GPA in his class and the BRASS scholarship for playing an active role in community service.
For his residency training, Dr. Pennesi spent his internship year in San Diego at Scripps Mercy Hospital, followed by his ophthalmology residency at the University of California, San Francisco. During residency he was awarded the Hogan/Garcia award for the best resident research project. After residency he completed an ophthalmic genetics fellowship under the tutelage of Dr. Richard Weleber.
Dr. Pennesi joined the faculty of Casey Eye Institute and is now an Associate Professor in Ophthalmic Genetics and as the chief of the Ophthalmic Genetics Division.
Both Research to Prevent Blindness and the Foundation Fighting Blindness have recognized Dr. Pennesi with career development awards to support his ambition to conduct transitional research that will bring treatments for diseases such as retinitis pigmentosa from the laboratory to the clinic. Additionally, he is the recipient of the 2011 ARVO/Alcon Early Clinician Scientist, the Alcon Young investigator Award in 2014, and the Casey Eye Institute Resident teach award. His research focuses on developing novel treatments for inherited retinal diseases. He is currently exploring the potential of a new class of drugs to up regulate protective growth factors in the retina.Read more

Doc Penesi is a great provider and human being. He is such professional and he shares his knowledge with his patients. He would not gives you illusions on care plans and at the same time he would try his best. His team as well, his assistant, the genetic counselor, and all his vision technicians are amazing. We are having the best experience ever , after years being seeing doctors and specialists, in U.S and Europe. We could not be happier and feeling more than blessed for being under their cares, especially when your loved ones have a such high grade diagnosis that sounds scary. Thank you all , for being a such excellent team and taking care of my precious daughter.Sincerely, [Name]

Dr. Pennesi was awesome! He didn’t seem in a rush and was happy to answer any and all questions we had.

I appreciate the level of care and considered thinking provided by Dr. Pennesi and also by Dr. Huber. Dr. Pennesi thinks about my situation and evaluates my current vision from the day's test results and decides how much has deteriorated since the last visit. Dr. Pennesi has an easy, upfront way of relating to patients. He discusses some things from a research or scientific view which is nice. He went over preventative measures to preserve my remaining vision, which is a good reminder. We are interested in participating in a clinical trial for my RP. Dr. Pennesi discussed the likelihood of that for my situation, and the different gene therapy methods developing. Dr. Huber asked me good questions before Dr. Pennesi's arrival and discussed gene therapy for the future. I hope I will see Dr. Huber next time as well when I am a patient at Casey Eye Institute.

Was very helpful and looked into things further than what I expected to have happen, and we were very pleased, because he was able to find out things that possibly can be helped with my eyes. So, thank you very much. Bye.

Living with blindness is scary for a teenager. Dr Pennesi has given me hope that if my vision was to get worse there are options to hopefully stop it or make it better.

Our son was diagnosed with RP, Dr. pennesi has been kind enough to sit with us and answer all our questions and concerns.

This was my first visit with Dr Pannessi. I thought he was very clear and helpful. He listened and was very personable..
- Aug 30, 2018
The staff are kind, but logistics are a nightmare. Every time I visit (Casey Eye Institute, specifically), we wait an exorbitant amount of time to be met. Yesterday, my son and I waited nearly an hour and a half in the room before the doc came to see us. In fact, I started walking out and found several staff, including the doc, standing in the hallway talking. I have a job, too, and if I asked any of the doctors to come to a meeting at my office, then made them wait nearly an hour and a half for the meeting to start, they wouldn't stand for it. It's unacceptable in every other part of society, yet happens regularly at Casey.

Exceptional knowledge of my disease. Always takes time to answer questions and to keep me updated on current research and possible treatments.
- Aug 17, 2018
He was compassionate and helpful. He understood my concerns, and had good alternative treatment for the disparity of acuity between my eyes. He gave me a prescription for sunglasses. He was encouraging about the possibility of clinical trials for my RP mutation to one day include females.
- Aug 03, 2018
We got the answers to our questions
- Jul 27, 2018
The doctor did not tell me if my vision got worse and never told me the numbers of each eye. Basically he did not tell me what I wanted to hear.
- Jul 22, 2018
I learned a lot, and I like the doctor.
- Jul 21, 2018
Not only was Dr. Pennesi very thorough and knowledgeable he is enjoyable to visit with. His staff and students are an added bonus very professional, knowledgeable and personable.
- Apr 12, 2018
Because Dr Pennisi is a specialist in eye disease, I would not recommend him to others.
